Description

Technical Field

[0001] This application relates to the field of energy storage box technology, and in particular to a portable home energy storage box. Background Technology

[0002] With the continuous development of energy storage and application technologies, portable home energy storage boxes are attracting increasing attention from users as important devices to meet the needs of home emergency power supply and outdoor power supply scenarios. To achieve mobility, some existing portable home energy storage boxes use fixed-mount casters, but this method has obvious drawbacks: the casters are always in contact with the ground, and they are prone to slipping due to accidental bumps when the energy storage box is placed, which not only poses a safety hazard but may also damage the internal components of the energy storage box; moreover, when the energy storage box needs to be fixed in place, the movement of the casters cannot be effectively restricted, making it inflexible in use.

[0003] In terms of handling and towing structure design, traditional home energy storage box handles have relatively simple functions. Most handles can only meet the single needs of handling or towing. To achieve the conversion between handling and towing functions, a complicated disassembly and assembly process is often required, which is cumbersome, time-consuming, and labor-intensive. It is difficult to adapt to the needs of users to quickly switch operating modes in different usage scenarios. In addition, the length of existing handles is usually fixed and cannot be adjusted according to the height and gripping habits of different users. This makes it difficult for users of different body types and strengths to find a comfortable gripping posture, and long-term use can easily cause fatigue, reducing the user experience. Therefore, a portable home energy storage box is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a portable home energy storage box to solve the problems mentioned in the background art.

[0005] The portable home energy storage box provided in this application adopts the following technical solution:

[0006] A portable home energy storage box includes an energy storage box body. Multiple guide rails are fixedly connected to the outer walls of both sides of the energy storage box body. Slide strips are slidably connected to the inner walls of the guide rails. Universal wheels are installed at the bottom ends of the multiple slide strips, and a top frame is fixedly connected to their top ends. A lifting mechanism for adjusting the height of the multiple universal wheels is installed between the top frame and the energy storage box body.

[0007] A handle is hinged to the top outer wall of the top frame via a connecting seat. A fixing component for fixing the handle is installed on the outer wall of the top frame. The handle includes a telescopic rod, a movable rod, and a crossbar. There are two telescopic rods and two movable rods. The movable rod is slidably connected to the inner wall of the crossbar. The crossbar is fixedly connected to the ends of the two movable rods located outside the telescopic rod. An adjustment component for adjusting the overall length of the handle is provided inside the movable rod.

[0008] Preferably, the lifting mechanism includes connecting rods and a two-way lead screw. There are two connecting rods, which are inclined relative to each other. The top ends of the two connecting rods are rotatably connected to the bottom outer wall of the top frame through connecting blocks. The two-way lead screw is rotatably connected to the top outer wall of the energy storage box through multiple bearing seats. Two nut rings are symmetrically threaded on its outer wall. A rotating shaft is fixedly connected to the outer wall of the nut rings. The rotating shaft is rotatably connected to the bottom end of the connecting rod.

[0009] Preferably, the top outer wall of the energy storage box is fixedly connected to two movable jaws, the two ends of the two rotating shafts are movably connected to the inner wall of the movable jaws, and one end of the bidirectional lead screw is fixedly connected to a handle.

[0010] Preferably, the fixing assembly includes two sliding frames fixedly connected to the outer wall of the top of the top frame, with sliders slidably connected to the outer walls of the two sliding frames, and a locking block fixedly connected to the outer wall of the slider facing the crossbar. A second spring is sleeved on the outer wall of each of the two sliding frames, and the second spring is located on the outer wall of the slider facing away from the locking block.

[0011] Preferably, the middle section of the crossbar has a fixing hole on its outer wall, and the end of the locking block away from the slider has an inclined surface that is adapted to and engages with the fixing hole.

[0012] Preferably, the adjustment assembly includes two movable slots formed inside the movable rod, with movable blocks slidably connected to the inner walls of the movable slots, and a limit block fixedly connected to the outer wall of the movable block facing the outside of the movable rod. A first spring is also installed inside the movable slot, and the first spring is located on the outer wall of the movable block facing away from the limit block.

[0013] Preferably, the telescopic rod has multiple adjustment holes arranged in an equally spaced array on both outer walls, and the end of the limiting block away from the movable block is designed in an arc shape and is adapted to be inserted into the adjustment holes.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. The set lifting mechanism allows for flexible lifting of the casters. When the energy storage box needs to be moved, turn the handle to drive the two-way lead screw, which in turn moves the nut ring and connecting rod, causing the casters to descend and contact the ground, easily supporting the energy storage box. Users can use the casters to move freely in 360 degrees. Whether moving between different rooms in the home or pushing it on complex outdoor terrain, it can easily cope with any situation. When it is not needed to move, turn the handle in the opposite direction to raise the casters off the ground, and the energy storage box is placed stably, avoiding safety hazards caused by accidental slippage, greatly improving the convenience and safety of use.

[0016] 2. The handle is connected to the top frame by a hinge and is equipped with a fixing component. When the handle is fixed to the top frame by the fixing component, the two are in a parallel state. At this time, the user can directly hold the telescopic rod for short-distance transport, which is simple and labor-saving. After the energy storage box is placed on the ground, the fixing component can be used to release the fixing of the handle and turn the handle to pull the energy storage box for long-distance movement. This realizes the flexible switching between the two modes of transport and towing, adapts to different usage scenarios, and significantly improves the convenience of use.

[0017] 3. The adjustable components inside the handle allow users to flexibly adjust the length of the handle according to their own grip habits and height differences. After pulling the crossbar to disengage the limit block from the adjustment hole, the movable rod can be pulled to slide inside the telescopic rod. After adjusting to the appropriate position, the limit block will automatically engage with the corresponding adjustment hole under the action of the spring force to achieve fixation. This ensures that users of different body types and different usage habits can find a comfortable grip length, effectively reducing user fatigue and improving the user experience.

Detailed Implementation

[0025] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0026] This application discloses a portable home energy storage box. (Refer to...) Figure 1-6 A portable home energy storage box includes an energy storage box body 1, which serves as the main structure of the entire energy storage box. The interior is used to install energy storage and control components such as battery packs and circuit boards. Multiple guide rails 2 are fixedly connected to the outer walls on both sides of the energy storage box body 1 by welding or bolting. The guide rails 2 extend along the height direction of the energy storage box body 1 to provide guide tracks for the sliding of the slider 3.

[0027] Multiple sliders 3 are slidably connected to the inner wall of the corresponding guide rails 2. The sliders 3 and the guide rails 2 are fitted with a clearance to ensure that the sliders 3 can slide smoothly within the guide rails 2. The bottom ends of the multiple sliders 3 are all equipped with casters 5, which are fixed to the sliders 3 with bolts. The casters 5 are equipped with brakes to facilitate the movement and fixation of the energy storage box. The top ends of the sliders 3 are all fixedly connected to a top frame 4. The top frame 4 is an I-shaped frame structure used to support and install other components.

[0028] A lifting mechanism is installed between the energy storage tank 1 and the top frame 4. The lifting mechanism includes a bidirectional lead screw 8 and two connecting rods 10. The bidirectional lead screw 8 is rotatably connected to the top outer wall of the energy storage tank 1 through multiple bearing seats 19. The bearing seats 19 are fixed to the energy storage tank 1 by bolts. The two ends of the bidirectional lead screw 8 are respectively provided with external threads with opposite directions of rotation. The two connecting rods 10 are arranged at relative inclinations, and the top ends of the two connecting rods 10 are rotatably connected to the bottom outer wall of the top frame 4 through connecting blocks 9. The connecting blocks 9 are fixed to the top frame 4 by welding. Nut rings 12 are symmetrically threaded to the outer wall of the bidirectional lead screw 8. The nut rings 12 and the bidirectional lead screw 8 are threaded together, so that the nut rings 12 can move axially when the bidirectional lead screw 8 rotates. A rotating shaft 11 is fixedly connected to the outer wall of the nut ring 12. The rotating shaft 11 is rotatably connected to the bottom end of the connecting rod 10. The rotatable connection is achieved through bearings to ensure the flexibility of rotation.

[0029] Furthermore, two movable jaws 13 are fixedly connected to the top outer wall of the energy storage box 1. The two ends of the two rotating shafts 11 are respectively movably connected to the inner wall of the movable jaws 13, providing support and limiting for the rotating shafts 11. One end of the bidirectional lead screw 8 is fixedly connected to a handle 14. The handle 14 allows the operator to manually rotate the bidirectional lead screw 8. When the operator rotates the handle 14, the bidirectional lead screw 8 rotates accordingly. Due to the threaded connection between the nut rings 12 and the bidirectional lead screw 8, the two nut rings 12 will move towards or away from each other on the bidirectional lead screw 8, thereby driving the connecting rod 10 to rotate around the connecting block 9 through the rotating shaft 11, realizing the raising or lowering of the top frame 4, thereby adjusting the height of the multiple casters 5. When it is necessary to move the energy storage box, rotate the handle 14 to lower the casters 5 to contact the ground and support the energy storage box 1; when it is not necessary to move, rotate the handle 14 in the opposite direction to raise the casters 5 off the ground and fix the energy storage box in place.

[0030] A handle 6 is hinged to the top outer wall of the top frame 4 via a connecting seat 7. The connecting seat 7 is fixed to the top frame 4 with bolts, allowing the handle 6 to rotate around the connecting seat 7. A fixing assembly for fixing the handle 6 is installed on the outer wall of the top frame 4. The fixing assembly includes two sliding frames 15 fixedly connected to the top outer wall of the top frame 4. The sliding frames 15 are cuboid in shape and are arranged in parallel. A slider 17 is slidably connected to the outer wall of the two sliding frames 15. A clearance fit is used between the slider 17 and the sliding frame 15 to ensure that the slider 17... 7. The slider 17 is able to slide smoothly. A locking block 18 is fixedly connected to the outer wall of the slider 17 facing the crossbar 603. The locking block 18 is used to lock the handle 6 with the crossbar 603. The outer walls of the two sliding frames 15 are fitted with second springs 16. The second springs 16 are located on the outer wall of the slider 17 away from the locking block 18. One end of the second spring 16 abuts against the slider 17, and the other end abuts against the end of the sliding frame 15. Through the elastic force of the second spring 16, the locking block 18 can always maintain the tendency to lock with the crossbar 603.

[0031] A fixing hole 6031 is provided on the outer wall of the middle section of the crossbar 603. The end of the locking block 18 away from the slider 17 is provided with an inclined surface, which is adapted to and locked into the fixing hole 6031. When the handle 6 is needed, the slider 17 is pulled outward to overcome the elastic force of the second spring 16, so that the locking block 18 is disengaged from the fixing hole 6031 of the crossbar 603. Then the handle 6 is rotated to the appropriate position. When the handle 6 is not needed, the handle 6 is rotated to reset it, the slider 17 is released, and under the elastic force of the second spring 16, the locking block 18 is inserted into the fixing hole 6031 of the crossbar 603 to fix the handle 6.

[0032] The handle 6 includes two telescopic rods 601, two movable rods 602, and a crossbar 603. The two telescopic rods 601 are symmetrically arranged at both ends of the crossbar 603. The crossbar 603 is fixedly connected to the ends of the two movable rods 602 located outside the telescopic rods 601. The movable rods 602 are slidably connected to the inner wall of the telescopic rods 601. An adjustment assembly for adjusting the overall length of the handle 6 is provided inside the movable rods 602. The adjustment assembly includes two movable slots 6021 formed inside the movable rods 602, which extend along the length of the movable rods 602. A movable block 6023 is slidably connected to the inner wall of the movable slot 6021. The movable block 6023 and the movable slot 6021 are connected... The two parts are fitted with a clearance fit. The movable block 6023 is fixedly connected to the outer wall of the side facing the movable rod 602 with a limiting block 6024. The limiting block 6024 is used to insert into the adjustment hole 6011 of the telescopic rod 601 to fix the position of the movable rod 602. The movable groove 6021 is also equipped with a first spring 6022. The first spring 6022 is located on the outer wall of the movable block 6023 away from the limiting block 6024. One end of the first spring 6022 abuts against the movable block 6023, and the other end abuts against the end of the movable groove 6021. Through the elastic force of the first spring 6022, the limiting block 6024 can always maintain the tendency to be inserted into the adjustment hole 6011.

[0033] Multiple adjustment holes 6011 are evenly spaced on both outer walls of the telescopic rod 601. The end of the limiting block 6024 away from the movable block 6023 is arc-shaped and fits into the adjustment holes 6011. When the length of the handle 6 needs to be adjusted, press the limiting block 6024 or pull the crossbar 603 directly to make it overcome the elastic force of the first spring 6022 and move it into the movable rod 602, thereby disengaging the limiting block 6024 from the adjustment hole 6011. Then pull the movable rod 602 to slide it into the telescopic rod 601 to the appropriate position. Release the limiting block 6024, and under the elastic force of the first spring 6022... The limiting block 6024 is inserted into the corresponding adjustment hole 6011, and the movable rod 602 is fixed on the telescopic rod 601 to realize the adjustment of the length of the handle 6 to meet the needs of different users. In addition, a display panel and operation buttons are provided on the front face of the energy storage box 1. The display panel is used to display the energy storage box's power, output voltage, current and other operating parameters in real time. The operation buttons are convenient for users to control the charging and discharging of the energy storage box, switch modes and other operations. The side of the box also has reserved power interfaces of various specifications to meet the charging needs of different electrical devices, further improving the practicality and convenience of this portable home energy storage box.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
